Read explanation below.



Radio wavelengths are immune to dust, unlike visible waves. This means that they can go straight through dust without being absorbed or reflected. This allows us to see what is happening inside gas and dust clouds.

Most of the universe is made up of hydrogen, most of which is too cold to emit in the visible spectrum but does emit in radio.
The biggest advantage is that they can operate day and night and in nearly any type of weather.


Since most Earth's communications rely on radio waves, from TV to phones to radio channels, radio satellite arrays must be built far away from cities and towns. Deserts areas are a go-to for radio telescope construction

The arrays must also be made up of several to dozens of large and precise antenna to pick up the wavelengths because they're very low energy.
